ABSTRACT

Landolphia owariensis is a plant common in West Africa with many ethnomedicinal uses. The leaves of the plant were investigated for phytochemical constituents. Successive extraction and chromatographic purification led to the isolation of two flavonoid glycosides myricitrin and quercitrin, and the triterpenoid and sterol glucoside, ?-amyrin and daucosterol, respectively. The compounds were identified by their NMR chemical shifts and comparison with literature reports.

Keywords: Landolphia owariensis, Apocynaceae, myricitrin, quercitrin, ?-amyrin, daucosterol.
